Korea

Presented to: UN Commission on Peaceful Uses of

Outer Space Scientific and Technical Subcommittee

February 2012 Presented by: Chin Young Hwang

Korea Aerospace Research Institute

Korea Aerospace Research Institute (KARI)

Introduction of KARI

- Established in 1989

- aims to contribute to the development of the national

economy and improvement of the quality of life in Korea

through research, technology leadership, development &

distribution on the aerospace science & technology field

- KARI with its 700 engineers/scientists plays a central role in the

aeronautics and space development of Korea

- In 2011, KARI spent about $270million in the aerospace R&D

sector and the investment is still increasing

KOMPSAT-2 Project within ESAs Third Party Mission Program

KOMPSAT-2 Ground segment co-operation: ESA has since long an operations contract with KSAT

for Tromso/ Svalbard facilities, with SISA for Cat-1, and aims to set up a long-term co-operation with KARI

ESA users are increasingly requesting to extend the Cat-1 Data Portfolio to VHR optical data

ESA supports the K-2 operations and in return gains the right to extract a quota of archived and new products

New TPM Co-operation scheme between ESA, European industry and KARI, and first time that TPM has a 1m satellite!
